THEODORE KOCHENKOFF, OI NEW YORK, N. Y.

CUFF-BUTTON.

Application filed May 13 1919.

[0 all whom it may concern.-

Be it known that I, THEODORE KOCHEN- new, citizen of the United States residing at New York, New York county, ew York Slate, hm e invented certain new and useful lmprovements in CuiflButtons. of which the "following is a specification.

This: invention relates to eutl' buttons and links and. its object is to provide means by which the device may rollapse and decrease in length when necessary to reduce the distance bet worn the button holes or it may be lengthened to provide a greater distance between the buttons above the elbow when the sleeves are raised and without loosening the connection. This is made possible by constructing the links of telescopic tubes of the desired number of sections and securing them against separation but adapting them to close in on themselves, as will be more fully described in the following specification, set forth in the claims and illustrated in the accompanying drawings which form a part of this application and wherein:

Figure 1 is a side view of the improved cu if buttons expanded.

Fig. 2 is a similar view in section.

Fig. 3 is a view of the links compressed and collapsed.

Fig. 1 is a plan view of the links separated.

Fig. 5 is a view of a blank of a link.

Fig. 6 is a side View of a modified form.

Fig. 7 is a similar view of another modified form partly in section.

While linen or other cufl's Will generally remain in a closed position and Where a short link is sulficient for a cufl button, there are occasions where the same will require expansion, particularly when the hand is passed through the cuff or it is desired to draw up the sleeves to elevate the cufis from the wrists.

The device shown in the drawings permits of this expansion and shows the two buttons 10 and 10 at each end of the intermediate links and these buttons may be of appropriate size and design. The button 10 is shown as being pivoted to the link 11 by means of a pin 12 so it may be thrown into a longitudinal position to enter the button holes to a V propriately locate the cuff buttons in the cud The links consist of tubes 11, 12, 13 and 14- oi (lifiorcnt sizes so that they telescope and Specification of Letters Patent.

assume the approximate size and shape shown in Fig. 3, and they are preferably arcshapcd to conform with the contour of the wrist or arm of the owner. As best shown in. Fig. i the tubes 11, and 1 re slotted and the tubes 1.5-. i and 12 are provided at their contiguous ends with lips if) to be bent downward to enter the slots of the snmller lube and it will be seen that in the use oil? lln' l'our links there are three slots l6 and throtlips. The links are tree to more inward or outward and are limited by the lcz-igth oi the slot only. the smaller links teltscoping with in the larger but the size of the tube may be such that the movement slow in conse quence of friction or tightness of lit and it will require manual. effort to close or open the buttons.

The construction of the intermediate links is illustrated in Fig. where the blank of the tube is shown with studs 11' and 18, the former for the lip 15 and front end oi? the slot and the'lattcr for the rear terminus of the slot. This blank is rolled into cylindrical shape for the tube. The blank for link 11 has no lip but two studs, and the link 14 has no studs because there is no slot to be formed.

The number ol: links for the button may be varied and also the shape, as shown in Fig. 6 where three links are used and adapted to operate in a straight line, and they are provided with appropriate lips and slots as above described.

The modified form shown in Fig. 7 provides tubes with an enlarged outer end and a reduced inner end so that the links 20 and 21 will freely pass into the tubes 21 and 22 respectively but will be arrested on account of the enlarged heads 23 being arrested by the contracted inner ends 24.

It is evident that other means may be adopted to hold the tubular links together Without departing from the essential features above described or from the scope of the appended. claims.

What I claim 'as new is:

1. In cllfi buttons, the combination of a series of tubular sections telescoping within themselves, buttons at the extremities of the series, and a lip at the end of the sections and adapted to engage the adjacent section and prevent their separation.

2. In cuff buttons. the combination of tubular telescopic sections having buttons at each extremity, and engaging means at the end of each section ndapted to enter it slot in the adjacent section.

I In cufi' buttons the combination of tubular telescopic sections with a button at the cm] of the first and luet sections, and a lip of the end of ouch hrrger section and ndupleii to phiy in a slot in the telescopic smaller section end prevent its separation.

in cuff buttons, the combinntion with a set of buttons, of tubular links of different iiimuetclrs adapted to telescope within each other and having slots, and menus playing in 1,310 slots preventing the separation of the he s.

5, In cuff buttons, the combination of a pair of buttons, a tube connected with one of the buttons and having a lip, and smaller tubes adapted to telescope within the first tube and having slots and lips to limit their movement and carrying the other button.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 9th day of May, 1919.
